Roll of a label web in the form of an Archimedean spiral of labels disposed one behind another

Abstract

Roll of a label web in the form of an Archimedean spiral of labels disposed one behind another and composed at least of a backing coated on one side with an adhesive, the labels being lined with a liner on the adhesive side, characterized in that the liner is diecut down to the labels and additionally forms a continuous web divided into individual sections, and the cut lines of the liner are located at an offset to the cross-cut lines of the labels such that beneath each label there is at least one cut line of the liner.

1 . Roll of a label web in the form of an Archimedean spiral of labels disposed one behind another and composed at least of a backing coated on one side with an adhesive, the labels being lined with a liner on the adhesive side, wherein the liner is diecut down to the labels and additionally forms a continuous web divided into individual sections, and cut lines of the liner are located at an offset to cross-cut lines of the labels such that beneath each label there is at least one cut line of the liner.  
   
   
       2 . Roll of a label web of labels disposed one behind another according to  claim 1 , wherein the labels disposed one behind another are each disposed at a distance from one another on the liner.  
   
   
       3 . Roll of a label web of labels disposed one behind another according to  claim 1 , wherein beneath a label there is only one single cut line of the liner.  
   
   
       4 . Roll of a label web of labels disposed one behind another according to  claim 1 , wherein the cut line of the liner is in the vicinity of a back edge of the label as viewed in a web direction.  
   
   
       5 . Roll of a label web of labels disposed one behind another according to  claim 1 , wherein the roll is wound such that relative to a roll center the liner represents an inner ply and the labels represent an outer ply.  
   
   
       6 . Roll of a label web of labels disposed one behind another according to  claim 1 , wherein the labels have a width of 20 to 25 mm and a length of 140 to 160 mm and the cut line of the liner is at a distance of between 20 and 30 mm from a back edge of the label.  
   
   
       7 . A method of producing an adhesive seal, comprising providing a label from the roll according to  claim 1 , passing the label around an article to be sealed, and sticking the label to itself.  
   
   
       8 . Method according to  claim 7 , wherein the label has a cleavable backing, so that when a seal of originality is broken open by pulling on the label, the backing cleaves irreversibly.  
   
   
       9 . Process for producing a roll of a label web of labels disposed one behind another and composed at least of a backing coated on one side with an adhesive, the labels being lined with a liner on the adhesive side, said process comprising the following steps: 
 a) producing a label stock material by furnishing a continuous backing layer with an adhesive,    b) applying the label stock material to the continuous liner,    c) diecutting the labels from the label stock material, by diecutting the label stock material down to the liner, producing one, or more adjacent label webs,    d) diecutting the liner on the liner side down to the labels, diecutting taking place in cut lines which lie crosswise relative to the web direction, the cut lines of the liner lying in each case at an offset to the cross-cut lines of the labels, in such a way that at least one of the cut lines of the liner is beneath the labels, and the liner additionally forming a continuous web divided into individual sections,    e) optiomally singularizing the adjacent label webs, and    f) rolling up the label webs to form an Archimedean spiral.    
   
   
       10 . Process according to  claim 9 , wherein the label stock material is cut by matrix cutting, the cut matrix being removed before the label webs are rolled up.  
   
   
       11 . Process according to  claim 9 , wherein the liner is cut before the label stock material.
